The Case of the Shifting Sarcophagus (Masked Man of Cairo‪)‬

An Old Kingdom coffin. A body from yesterday.

Sir Augustus Wall had seen a lot of death. From the fields of Flanders to the alleys of Cairo, he's solved several murders and sent many men to their grave. But he's never had a body delivered to his antiquities shop encased in a 5,000 year-old coffin.

Soon he finds himself fighting a vicious street gang bent on causing national mayhem while his assistant, Moustafa Ghani, faces his own enemies in the form of colonial powers determined to ruin him.

Throughout all this runs the street urchin Faisal. Ignored as usual, dismissed as usual, he has the most important fight of all.
